摘要

Uranium, a primordial radionuclide, poses potential risks to human health due to its radiological and chemical toxic effects. Its presence in groundwater resources has raised increasing public health concerns, especially in regions where groundwater is the main source of drinking water. This study systematically evaluates uranium concentration in potable water from the Tons valley, which is a tectonically active area in Garhwal Himalaya. The concentration of uranium in the water samples was determined using Inductively Coupled Plasma Mass Spectrometry (ICP-MS). Uranium concentrations were measured below the WHO guideline values in all the studied samples. The estimated health risks from uranium exposure through drinking water in this area were observed to be minimal. These results improve understanding of geogenic uranium distribution in Himalayan aquifers and provide important baseline data for ongoing and future environmental monitoring.
